Tracks missing from beatport?

Am I the only one who notices some things will be on Beatport one day and then be gone the next? I spin a lot of jump up and am always buying old tracks digitally to replace some vinyl when I have money and can find the tracks. Anyway this has happened before but I had a few tracks from Mickey Finn's label Finn People saved to my hold bin and now the ENTIRE label is no longer on Beatport. Does anyone know the story, not with this example per say, but why this happens in general?
